GT Fulvic – Concentrated Fulvic Acid Bio-Stimulant for Hydroponics (1L, 5.5L, 20L)

Make Every Nutrient in Your Tank Work Harder

GT Fulvic is a concentrated fulvic acid solution that supercharges your existing nutrient programme. Added to your reservoir, it acts as a natural chelating agent — bonding with mineral nutrients and making them significantly easier for your plants to absorb. The result: higher mineral uptake, faster cell growth, and noticeably better plant performance without changing anything else in your feed schedule.

What Fulvic Acid Actually Does for Your Plants

• 🌱 Increases mineral uptake — chelates nutrients in solution, making them more readily absorbed through the roots
• 🌱 Speeds up mineral transport within the plant — increases cell membrane permeability so nutrients move faster once inside
• 🌱 Stimulates cell division — drives enhanced cell growth which directly translates to faster, more vigorous plant development
• 🌱 Improves nutrient efficiency — get more out of the nutrients you’re already using without increasing dose rates
• 🌱 Supports plant health and yield — higher mineral levels in plant tissue means healthier growth and better harvests
• 🌱 Compatible with all hydroponic systems — recirculating, run-to-waste, coco, NFT, flood & drain

How to Use GT Fulvic

GT Fulvic is highly concentrated — always dilute in your nutrient solution before use. Add it whenever you make a fresh batch of nutrients.

Recommended dose range: 2–5ml per litre (50–125ppm fulvic acid in tank)

• 2ml/L = 50ppm — lighter feeders and sensitive plants
• 3ml/L = 75ppm — general use, most plant types
• 4ml/L = 100ppm — heavier feeders in active growth
• 5ml/L = 125ppm — heavy feeders at peak demand

Recirculating systems: Add GT Fulvic each time you refresh your reservoir (weekly recommended).

Run-to-waste systems: Add once when making up your nutrient solution.

Tip: GT Fulvic works with any base nutrient — GT Coco, GT Optimum, or any other brand. It enhances what’s already in your tank.

Choose the Right Size

• 1L — ideal for home growers and small systems
• 5.5L — great value for regular growers running ongoing cycles
• 20L — best value for large-scale grows and commercial operations
